Numato 2 Relay breakout module is a smart choice for controlling higher current loads from your microcontroller development board or a PC parallel port. This board has two on-board relays which can switch up to 10A. All relay terminals (C, NC, NA) are accessible through screw terminals which makes wiring up the board very easy.  The relays are driven by popular darlington array ULN2003. Relay coil is rated for 12VDC.

• Very compact and easy to wire up

• 1.6mm FR4 PCB with black solder mask and white silk screen component print

• Connects directly to TTL devices (Microcontrollers, Arduino etc..) 

• Two Relays with one three pin screw terminals for easy connectivity
